The Lord of the Rings novels by "Fantasy Fire-hydrant" J.R.R Tolkien
Here's everyone's precious: Gollum. From corrupted Hobbit to superstar celebrity, Gollum has come quite a ways to frantically burrow his way into our hearts.
Gollum appeared The Hobbit and kept sneaking around throughout the LOTR trilogy. When he wasn't eating raw fish, Gollum liked to conspire and plot to get his Precious back. Well, half of this character's personality would plot, anyway. You see, all those years under the power of the One Ring had deformed what was originally an upstanding hobbit named Sméagol. Extending his life and ravaging his body, the One Ring asserted itself as Sméagol's master.
After Bilbo happened upon the Ring (it had been momentarily misplaced by a certain slimy little character), Gollum set out in search for his Precious (the One Ring). He was eventually captured by the forces of Mordor and through torture revealed the words "hobbit" and "Shire." This pretty much put events in motion for LOTR.
Anyway, above is a drawing of Gollum being all "GIVE ME MY PRECIOUS. IT BELONGSES TO ME!"
Here's the b/w version, just so you can see how it looked before the coloring process:
